BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention covers an innovative means of electric propulsion, validly supported by a special harness that can be used by scuba divers, deep-sea divers or simple amateurs, the entire apparatus advantageously powered by a sophisticated system of rechargeable batteries inserted inside various water tight containers joined together by means of interstices of rubber or other suitable technical material. As we know, the greatest difficulty faced by anyone working underwater is moving around. This difficulty, in certain particular conditions, increases exponentially, very severely testing the resistance even of the most qualified persons who, even if adequately prepared, can incur serious risks that can endanger their safety. The innovative structure will allow all amateurs or other specialized operators to move underwater without any problem, even if they are submerged in deep water for long periods of time. Another very important characteristic of the system is its reduced size, which will make it possible to move and work in complete freedom and under any conditions.
